Do you need to know Network Virtualization ?

06/03/2017

Why NV?

20170304-01I recently took the VMware Certified Professional 6 Network Virtualization Exam. Preparation for a technical exam like one of the available VCP exams takes a lot of your free time, so why choose this one?
In recent years, I increasingly encountered the product NSX Manager, usually in VDI deployments with endpoint protection products like McAfee Move, Trend Micro Deep Security, to name a few. And while working on the upgrade of a VMware View environment, also comes the question, how to handle the endpoint protection part; How do we upgrade these components?
In the concept of the SDDC, besides the well known Compute and Memory providers, I consider Storage virtualization (like vSAN) and Network virtualization (NSX) as fundamental building blocks that should be part of your “basic” VMware knowledge.
I also noticed that VMware is doing a lot of promotion for the subject of micro-segmentation, and for a good reason.
So, I decided the time has come, to extend my knowledge. So where do you start? If you are on a VCP-DCV level, but cannot tell the difference between layer 2 and layer 3, I recommend start reading a book like “Networking for VMware Administrators” by Chris Wahl and Steve Pantol.
At that time, I was in between jobs with no budget, to attend regular VMware training courses like the “VMware NSX – Install, Configure and Manage” course.

All Hands on Deck / VMware

19/02/2017

201701-01Although VMware is best known for its core virtualization product vSphere, it may not come as a surprise that since their first product releases, a lot has changed. Over the years, on top of this solid foundation, VMware built a “Software Defined Everything” stack (SDDC), a Cloud stack with all the Automation and Orchestration tools, Monitoring tools, an End User Compute environment etc. This has led to a very large number of VMware products.
As you are as curious as I am, product
data sheets and documentation maybe helpful, but the best way in my humble opinion is to download, install and try the bytes yourself.
In addition to options already there, VMware launched a new one; Product Walkthroughs. So time for an overview how to get familiar with these fine products.

OpenStack lab – Part 2

28/12/2016

In the previous post, we described the installation of an OpenStack lab on a single (physical) host. In this post, we will continue.

First, we will perform some checks and see if our OpenStack environment works as expected. I will also show some useful commands for troubleshooting, how to start and stop your environment.

We will also have a look at the GUI components and finally we will create our first stack.

Does it work as expected?

To check the result of our work, from our “normal” user account logon tot the oslcontroller:

$ ssh – A root@oslcontroller

From there run the following command to check the status of OpenStack:

# openstack-status

You will get a very detailed overview as OpenStack admin

# source keystonerc_admin

# openstack-status

OpenStack lab – Part 1

27/12/2016

Introduction

20161222-01OpenStack is a well known open source cloud platform, most often in the form of IaaS. The development of OpenStack is controlled by the OpenStack Foundation and is supported by dozens of well known companies.

Although VMware has its own proprietary cloud platform, the company is also an active contributor to the OpenStack community and also developed VMware Integrated OpenStack. VMware Integrated OpenStack lets you rapidly deploy an OpenStack environment based on VMware’s own ESXi hypervizor and NSX. Fine for a production environment but not suitable for a simple lab. Apart from VMware licenses, the biggest drawback, you will need an awful lot of hardware for such a lab.

For some time I was searching for a way to have an OpenStack lab environment with some real life features. Recently, the dutch version of Computer magazine C’T published an interesting article how to build an all-in-one OpenStack environment, some specifications:

  • The whole environment runs on a single host with Fedora 24.
  • The host runs 5 Open VZ containers. The containers run 1 controller node, 3 compute nodes and 1 network node.
  • The nodes are connected with each other and the outside world by means of Virtual Networks based on libvirt, see for more information this link.
  • On these nodes are installed and configured the following OpenStack services: Nova, Glance, Keystone, Horizon, Neutron, Swift, Cinder, Ceilometer and Heat.
  • OpenStack components are installed and configured with help of Packstack, which uses Puppet modules controlled by an answer file to deploy the OpenStack Components.

I started with installing an old HDD drive in a old ESXi host (HP ML 110 G5) with only 8 GB of RAM. After finishing the installation and configuration of the host computer, the complete environment is created by running just 4 scripts!

When your choice of storage is NetApp or you want to know more about managing NetApp, please read on.

How to Build a NetApp ONTAP 9 Lab” is a free available guide, written by Neil Anderson at Flackbox.com. This almost 120 pages step-by-step guide walks you through the setup of a lab consisting of two NetApp ONTAP Clusters, including clients, routers, IP address tables etc. The best part, you can build the entire lab for free, all you need is a PC with preferable 16 GB of RAM (if you want to run ONTAP v8.2, 8 GB RAM will do).
